What are three environmental issues and the relevance/significance that they have on the environment?
There are several environmental issues that the planet is facing today. They are all by definition significant to the environment. I will outline three of them below.
Climate change is probably the environmental issue that you hear about most regulary from the media/news. There is little doubt that the Earth is in a warming phase right now. Outside of the question of the effect that will have on weather and living organisms, the rise in sea level from melting polar ice could affect millions of people inhabiting coastal areas The key question here is if the warming is part of a natural cycle or if it is caused by humans. The Earth has gone through numerous dramatic climate changes in the past before humans ever existed and certainly before the burning of fossil fuels. But the flip side to the question is even if man is accelerating the warming, what can we really do about it? The Western world's entire lifestyle is ultimately based on combustion, thus producing the greenhouse gas CO2. And the Eastern world is quickly catching up with Western lifestyles. Do we have the technological means and the trillions of dollars to alter this combustion-dependence on a global scale?
Agriculture and food production is another major topic. The Earth's population is growing at a rapid pace and it will be many more years before the growth starts to level off. We need more food to feed all of these people. But how do we feed everyone without turning more forests into farmland? And how do we maintain the farmland that we have now and prevent it from being used up and becoming unusable?
Water conservation is another major topic. Although water covers most of the planet, most of it is saltwater that is not directly usable. And of the freshwater supplies on the planet, much of it is tied up in polar ice. Only about 1% of the water on the planet is directly usable by people. And increasing global temperatures are only going to increase the stress on the water supply. We need to cut down our water usage and step up conservation efforts to protect the water that we do have and pretect ourselves from being so vulnerable to drought.
♣ Environmental issues that have bad consequences on our environment:-
♦ GLOBAL WARMING - it is the matter of great worry that the ozone layer has got a hole into it which is very dangerous. due to this many ultraviolet rays enter our safe surrounding. This hole in the ozone is caused by the vehicles, industries which we run, it releases carbondioxide which traps the heat into the earth making the earth more warmer. due to this glaciers are melting and sea levels are rising which is nothing but a call for disasters.
♦ GROWING POPULATION - I think that it is the most main and very cause of our destruction, every disasters either natural or socially, economically , financially based are caused by this huge crowd only.
♦ RETARDING WATER LEVEL - as the population is increasing they are utilising more and more water which is the most vital and useful substance to carry out bilogical as well as chemical processes in side and outside the body.
♦ LESSER AGRICULTURAL PRODUCTION - growing population needs more food and these food can be only utilised from lands so, lands are pressurised for production making them infertile for use.
♦ AIR, WATER, SOIL POLLUTION - our growing activities is providing many pollutants to our surrounding mediums making it unfit for further uses. these mediums are very important to support life and i cant think life without such contents.
♦ DEFORESTATION - trees are the mans best friend not only in one aspects but in many, the things which it provides to us are really uncountable but still people bring down their best friends without no hesitation.
