Does it seem like the monsoon has given up on a schedule and does just as it pleases? Does it seem weird that there are freak storms and floods? Do you see the green cover rapidly shrinking on Planet Earth and the pollution levels rising? All this is a result of our deteriorating environmental conditions. The biggest cause being global warming- the root of all other causes. The current environmental problems our Planet Earth is facing include ozone depletion, pollution, loss of natural resources, nuclear problems, loss of biodiversity, energy crisis, improper waste management and the biggest of hem all, global warming.Chlorofluorocarbons (CIFS) are considered to be the main cause of ozone depletion. The term ozone depletion implies a decline in the quantity of ozone in the earth’s stratosphere.
The loss of ozone in the lower stratosphere was first recorded in Antarctica in the sass. As we know, the earth’s atmosphere is composed of many layers; ozone forms one such layer in the stratosphere. CIFS are used in aerosol sprays as well as air conditioners. These, when released into the atmosphere add to the ozone depletion.
The ozone hole in the Antarctic is caused primarily due to these CIFS- Due to zone depletion; humans are faced with various other problems such as dealing with the harmful effects of IV rays. These affect not only humans, but also affect plants and various species of animals as well. Pollution is something that we face on an everyday basis.
It is probably a problem that we may have become immune to, given our fast-paced lives and the fact that it is being treated as a hackneyed issue, where a lot is spoken about but nothing concrete is ever done.Pollution can be divided into four main categories: air pollution, water pollution, soil pollution and noise pollution. Air pollution occurs with the addition of harmful chemicals into the earth’s atmosphere. The main pollutants of air are carbon monoxide, CIFS (Chlorofluorocarbons), nitrogen oxides and sulfur dioxide. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time.
The sources of air pollution are both natural and human-based.As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Water pollution is caused when wastes are released into the water and contaminates it. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. Soil pollution takes place when the soil is contaminated due to various industrial activities.It has been mainly attributed to arbitration and industrialization, both of which destroy natural resources that are already present in order to build and become successful.
Noise pollution occurs when the noise levels (honking, loud speakers, etc. ) roses the normal decibel level. This can have a harmful effect on one’s hearing and lead to more severe after-effects, both physical and psychological (fatigue, irritation, Stress, etc. ). With the alarming rate of increase in population, the loss of natural resources has become one of the major concerns.
Issues like deforestation, animal extinction, shortage of water, lack of space and food are only some of the concerns brought on by the lack of resources. There are many reasons that lead to the loss of natural resources (increasing demands brought on by population explosion, disregard for nature, human greed). This, in turn, affects the varied ecosystems. Activities such as overfeeding and hunting have even led many species of fish and animals respectively to the brink of extinction.Forests are being cleared to meet the rising demands for the need of paper, wood and land. Mining and burning of fossil fuels have led to further depletion Of resources.
Then again, this is merely scratching the surface. Nuclear energy is generated from the splitting of uranium atoms. This energy is used to create steam, which in turn is used to produce electricity. While there are definite advantages of generating nuclear power, what stands equally true is the fact that the process of producing the same harms the environment in many ways.
The process of converting uranium into usable energy produces radioactive waste (2000 metric tons of radioactive waste is generated in a year in the USA alone), which is extremely harmful for human, animal and plant health at many levels. Along with that, the storage of nuclear power ATA plant, as well as the fact that most other equipment in the plant will also convert into radioactive material over time and remain radioactive for several years is a major threat. While decaying, radioactive material releases certain particles, which leads to damaging effects on health, like cancer.Along with these health concerns, production of nuclear energy also leads to several other harmful effects like emission of carbon dioxide (during mining, transport, waste management and other processes of producing nuclear energy), usage of excessive water and water discharge. This will, in turn, affect the environment at many levels.
Biodiversity refers to the combination of a diverse range of species on earth. The varied plants, animals and microorganisms, the different ecosystems coral reefs, deserts, rain forests, etc. ) all have a unique role to play in the cycle of earth.
These diverse species lead to the boost of varied ecosystems, which thus enables them to prevent, as well as recover from several disasters. However, due to varied human activities like deforestation, and hunting, the natural habitats as well as the survival of several species are being threatened. Several plant and animal species are on the verge of extinction, while others have already become extinct. The extinction of animals and plants can lead to varied effects, some of which are – increase in sea levels leading to floods), droughts, wildfires, forest destruction and more.
The impact of energy on human life is probably only second to agriculture and forestry. That having been said, the negative impact that energy, as a source, has on the environment is quite far-reaching. Energy of any kind, may it be thermal, hydro, and nuclear or electric has led to several environmental concerns. Where earlier the concerns were restricted to the local arena, the issues have now become global. Energy and the activities related to energy production lead to hazards of some form or the other.
Extraction of raw trial for production (emission of carbon dioxide), transportation, and the conversion to usable forms of resources have harmful effects. Along with that, it has also led to concerns like acid rain, the greenhouse effect as well as global warming. Wastes can be of several kinds (industrial, nuclear, chemical, domestic), and each can lead to environmental degradation. From excessive plastic used at home to the radioactive waste produced by nuclear plants, the impact can be disastrous.
Not only are these wastes harmful on their own, but the techniques (or the lack) of waste management and disposal adds to this robber manifold. Emissions from industries as well as toxic by-products like mercury, crude oil, plastic and lead are not properly disposed off. They are dumped into the oceans and soil, thus leading to disastrous impacts on all life forms. Of these, oil spills have become another major concern.
These wastes lead to the destruction of natural habitats of both plants and animals and other species as well, in both land and water.They therefore make the environment toxic. Along with increasing the risk of extinction of several species, it also leads to other health concerns such as the development of total diseases like cancer and lead poisoning. One of the biggest issues facing us right now is global warming.
The term signifies an increase in the atmospheric temperature near the earth’s surface, which is caused due to various reasons. Scientists are of the opinion that a rise in the carbon dioxide levels will further aggravate the situation.Carbon dioxide emissions from burning gasoline for transportation, deforestation (especially tropical forests for wood, pulp, and farmland), increase in usage of chemical fertilizers on croplands, rise in sea levels, worldwide massive crop allures, widespread extinction of species are the main effects of global warming. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperatures. Global warming has thus caused a change in the climate of the earth, causing temperatures to rise.This, in turn, has an effect on various species dependent on the basic laws Of nature. A change in the same makes survival a difficult issue. A warmer earth also causes changes in the rainfall patterns and thus affects humans, plants and animals as well.
The effects of global warming on animals ND on agriculture are indeed frightening, and the effects on the human population are even scarier. The facts about global warming are often debated in politics and the media, but, unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable.The causes are mainly from us; the human race, and the effects on us will be It’s impossible to reduce one’s negative environmental impact to zero, so the hope has always been to reduce man’s negative impact as much as possible and then to increase our positive impact.
In other words, we reduce the harm e do to the planet and increase the good we do in the hope that, ultimately, we will have no net impact. Humans should not think of themselves as owners or inheritors of the earth or that they have a right to dispossess every other living creature of its habitat to feed himself and his kind.We should not covet the buried riches of earth as much as we do now but also learn to appreciate the beauty created by mother earth on the surface.
Our goal should be sustainable development. Both using and protecting resources in such a manner that they are available to the generations that moms after us. Sustainable development will depend not only on continued research and application of ecological knowledge. It will also require us to connect the life sciences with the social sciences, economics, and humanities.Conservation and restoration of diversity is only on side of sustainable development; the other key facet is improving the human condition. Public commitment and cooperation of nations are essential to the success of this endeavor. Each of us must play our part, no matter how small, if this is to become a reality.
Environmental protection awareness is at its peak. Measures have been taken to educate as many people as possible about our decaying planet. But why is it necessary? One billion people in the world have no clean water. Two billion people have inadequate sanitation.One and a half billion people (mostly in large cities of newly industrialized countries) breath air that is dangerously unhealthy. Hundreds of millions of poor farmers struggle to make a living on poor land. Whole countries are on the verge of famine. Therefore, it is high time we start protecting our environment.
Luckily enough, protection has already started. It is more profitable to prevent pollution rather than deal with it after it has spread. To stop pollution before it is caused is the best course. Hence contain modernization in equipment Of environment management is also important.Where there is awareness among the people, the pressure on the government to control pollution is more. Measures have been taken to control water pollution in cities and villages. Solid waste, which is thrown into the lakes, mixes with the water and pollutes it.
That is why waste needs to be separated into dry and wet wastes. The wet waste needs to be composted for agricultural use. Land pollution is controlled by exploring the possibility of recycling hazardous wastes as raw material in another process.
People in many countries have now taken up recycling. It is another way to reduce and control soil pollution.Recycling paper, plastics and other materials reduces the volume of refuse in landfills, another common cause of soil pollution. Many countries have reduced or completely banned the distribution of plastic bags and have promoted the use of cloth or paper bags as a substitute.
Deforestation has been reduced due to strict laws. Certain countries follow the policy of planting new tree with each tree that has been felled. Noise pollution has also lessened. Excessive honking vehicles is one of the biggest contributors to noise pollution. However, people are now aware of its dire effects and have taken incentives to control it.Strict laws have also been passed. Loud music is not to be played beyond a certain time. Air pollution has also been controlled recently.
Many industries have been given a carbon limit. They are not to exceed the given limit Of carbon released and if they do, hefty fines are to be paid. People have started using hybrid icicles that do not release as much of dangerous gases as normal cars do. People have been made aware of the harmful effects of cigarette smoking. Endangered animals are being protected by transferring them to zoos, natural reserves etc.
Where they are being made to breed.Strict laws have been passed to ban hunting, poaching and illegal smuggling of animals. Overfeeding has also been reduced with the introduction of certain rules and regulation. For example, fishermen aren’t allowed to fish beyond a certain limit from the shore. They arena allowed to fish during the breeding season either.
The world is moving towards a sustainable energy future with an emphasis on energy efficiency and use of renewable energy sources. We depend on energy for almost everything in our lives. We wish to make our lives comfortable, productive and enjoyable.Hence even if the outside temperature rises a little, we immediately switch on the air conditioner to keep our house cool.
This is again using up of energy. Unfortunately, what we do not realize is that We have starting taking things for granted and we have started wasting energy unnecessarily. Most of us forget that energy is available in abundance but it is limited and hence to maintain the quality of life, it is important that we use our energy resources wisely. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere.This has in turn led to many problems being faced today such as ozone depletion and global warming. Vehicular pollution has also been a major problem. Therefore, alternative sources of energy have become very important and relevant to today’s world.
These sources, such as the sun and wind, can never be exhausted and therefore are called renewable. Their use can, to a large extent, reduce chemical, radioactive, and thermal pollution. They stand out as a viable source of clean and limitless energy. These are also known as non- conventional sources of energy.
Most of the renewable sources of energy are fairly non-polluting and considered clean though biomass, a renewable source, is a major polluter indoors. Earth is four-and-a-half-billion-years-old. There’s been life on it for nearly that long, 3. 8 billion years. Bacteria first; later the first multicultural life, then the first complex creatures in the sea, on the land. Then finally the great weeping ages of animals, the amphibians, the dinosaurs, at last the mammals, each one enduring millions and millions of years, great dynasties of creatures rising, flourishing, dying away all this against a background of continuous and violent upheaval.There have been commentary impacts, volcanic eruptions, rise and fall Of oceans, whole continents moving, an endless, constant, violent change, colliding, to make mountains over millions of years.
Earth has survived everything in its time. It will certainly survive us. If all the nuclear weapons in the world went off at once and all the plants, all he animals died and the earth was sizzling hot for a hundred thousand years, life would survive, somewhere: under the soil, frozen in Arctic ice. Sooner or later, when the planet was no longer inhospitable, life would spread again.The evolutionary process would begin again. It might take a few billion years for life to regain its present variety. Of course, it would be very different from what it is now, but the earth would survive our folly, only we would not. If the ozone layer gets thinner, ultraviolet radiation sears the earth, so what? Ultraviolet radiation is good for life.
It’s powerful energy. It promotes tuition- change. Many forms of life will thrive with more IV radiation.
Many others will die out. Is this the first time that’s happened? Think about oxygen.Necessary for life now, but oxygen is actually a metabolic poison, a corrosive glass, like fluorine.
When oxygen was first produced as a waste product by certain plant cells some three billion years ago, it created a crisis for all other life on earth. Those plants were polluting the environment, exhaling a lethal gas. Earth eventually had an atmosphere incompatible with life. Nevertheless, life on earth took care Of itself.
In the thinking of the human being a hundred ears is a long time. A hundred years ago we didn’t have cars, airplanes, computers or vaccines.
