Introduction.
Our environment is constantly changing. With a massive
influx of natural disasters, warming and cooling periods, different
types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing.
All across the world, people are facing a wealth of new and challenging environmental problems every day. Some of them are small and only affect a few ecosystems, but others are drastically changing the landscape of what we already know.
Our planet is poised at the brink of a severe environmental crisis. You will see 8 Major Current Environmental Problems.
Слайд 3
Pollution
Pollution of air, water and soil require millions
of years to recoup. Industry and motor vehicle exhaust
are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
Слайд 4
Global Warming
Climate changes like global warming is the
result of human practices like emission of Greenhouse gases.
Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
Слайд 5
Overpopulation
The population of the planet is reaching unsustainable
levels as it faces shortage of resources like water,
fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
Слайд 6
Waste Disposal
The over consumption of resources and creation
of plastics are creating a global crisis of waste
disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
Слайд 7
Loss of Biodiversity
Human activity is leading to the
extinction of species and habitats and and loss of
bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
Слайд 8
Ozone Layer Depletion
The ozone layer is an invisible
layer of protection around the planet that protects us
from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.
Слайд 9
Genetic Engineering
Genetic modification of food using biotechnology is
called genetic engineering. Genetic modification of food results in
increased toxins and diseases as genes from an allergic plant can transfer to target plant. Genetically modified crops can cause serious environmental problems as an engineered gene may prove toxic to wildlife. Another drawback is that increased use of toxins to make insect resistant plant can cause resultant organisms to become resistant to antibiotics.
Слайд 10
Acid Rain
Acid rain occurs due to the presence
of certain pollutants in the atmosphere. Acid rain can
be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.

Conclusion
The need for change in our daily lives
and the movements of our government is growing. If
humans continue moving forward in such a harmful way towards the future, then there will be no future to consider. Although it’s true that we cannot physically stop our ozone layer from thinning, there are still so many things we can do to try and put a dent in what we already know. By raising awareness in your local community and within your families about these issues, you can help contribute to a more environmentally conscious and friendly place for you to live.
