Top 10 Environmental Issues

Global warming is one of the biggest threats to this planet. Read on to know what are some of the top 10 environmental issues that need to be addressed with immediacy.
Environment is a resource, which is being consumed at an exponential rate. Unfortunately, this resource cannot be easily replenished. This has led to a lot of environmental concerns and issues which need to be dealt with on a war footing. The global scenario today is fraught with drought, famines, floods and natural calamities.
The frequency of such occurrences is increasing in a dramatic fashion. Here we take a look at what are the serious environmental issues the world is facing today. Most of them are interlinked and might have the same cause. They are listed separately as the strategies that need to be undertaken to combat them might be different.

Chemicals, Toxic Waste and Heavy Metals

Lot of emissions created by humans contain high amounts of chemicals and toxins. These have an adverse effect on the environment.

Climate Change

The Inuits are one of the main races to be affected by the climate change phenomena.
Their first hand reports complain of rising temperatures in summers, winters not being cold enough and the freezing land mass that cause reduction in land masses. Climate change has bought upon severe droughts in some regions.

Waste Management

Closely linked with the rapidly growing population across the world and the rate of consumption, waste, and its management has become a major issue around the world. We need to shift our focus to reuse instead of the throwing out option.

Biodiversity and Land Use

The term biodiversity essentially means variety of life that exists in any given area. High demand for food, clothing and shelter has led to a skewed land use pattern. More land is coming under cultivation which may lead to problems of water shortage and land salinization.


This is a major issue that might be seen as a cause of many other environmental issues.
Consumption can be dealt in a very effective way. We definitely cannot reduce the population of the earth overnight, but we can definitely educate the masses about smart consumption.

Water Scarcity

Only 2% of the water available on Earth is pure and fit for consumption.
Many regions also depend on rainfall as the source of water, with the rainfall patterns changing across the world due to climate change, some regions have been affected severely with droughts and famines. At the same time, too much of rain has also caused flash floods across some regions destroying natural and man-made ecology of the region.

Wanton Deforestation

Deforestation can be seen as a trickle down effect of increase in consumption, change in land use and also increase in quantum of waste generated.
Increase in consumption of food has led to a lot of forest area being used for cultivation. Deforestation also takes place around urban areas when they expand to accommodate more population. The green cover reduces globally and causes more damage to natural ecosystems and climate system of the world.


Renewable or non-renewable sources of energy, their demand and consumption is a cause of environmental concern around the planet. Any source of electricity, thermal, hydro or nuclear has a flip side of environmental problems.

Ecosystem and Endangered Species

People usually take ecosystems for their aesthetic value, but the function of ecosystems and the species that exist in them can be multidimensional and extremely important to maintain an ecological balance. Conservation of ecosystems and endangered species is often neglected as an issue, but still remains a very critical environmental issue.

Science of Genetics

This is a very sensitive and highly debatable issue. Are we right to play God and tamper with nature?
Science has helped humans a lot and has achieved lot of breakthroughs in terms of medicine, technology, health, communications, etc. In fact, all aspects of human life are improved tremendously with the help of science. Genetic modifications of plants, animals and probably even humans in the near future may cause more damage than good.
The toughest challenge is spreading awareness and educating people about the degeneration of green resources, that the planet is facing. Many of the issues are caused because of the lifestyles we follow, without a sense of consequence.
There is a burning need to lead a much more sustainable way of life and make more people adapt to it as soon as possible. We have only one planet, only one home, let's not lose it to our greed!
