There is no denying fact that our environment is constantly changing so does the need to become aware of the problems surrounding it such as change in warming and cooling periods, weather pattern changes, massive influx of natural disasters and much more. As we are indiscriminately using our natural resources and fail to manage our waste, environmental condition is heading towards much worst. The events of heat waves, glaciers melting, floods have been extreme during past few years.
Our environmental condition is deteriorated to such an extent that its effect can be seen on our daily life and yet we are not concerned to save ourselves from its effects. Due to pollution, different types of natural calamities, extinction of many species create imbalance to food chain.
It is also true that only human beings are responsible for polluting environment.
Here I have listed some megatrends which present major global threats for planet earth-problems that must be solved if the world is to remain a supportive habitat for humans and other species.
Population explosion: The first and foremost emerging problem in the world is population explosion. Increased population growth results in overexploitation of our natural resources indiscriminately posing negative effect on environment and its vital elements such as air, water, fuel, food etc. Intensive agriculture to meet the requirement of food are also damaging environment through use of chemical fertilizer, insecticide and pesticide.
Global Warming and Climate change: Huge carbon dioxide production due to increased human activities resulted in climatic changes like Global warming. Global warming leads to rising of earth surface temperature causing melting of polar ice caps, rise of sea level and unnatural patterns of natural calamities like flood, drought , change in seasons and occurrence of new diseases.
Waste Disposal: Production of an excessive amount of waste (Including nuclear waste) and garbage and its disposal into oceans, open places has tremendous health hazards. At present situation is so dangerous that not only the land area but also the sea land area is highly polluted posing harmful effects to human beings and sea living species. Mismanagement of industrial waste is the main reason for area and water pollution.
Deforestation: Destruction of forest results in increase concentration of carbon dioxide in our environment that create several types of natural disaster every year. At present frequency of disaster are increasing per year causing irrecoverable economical loss and destruction of thousands of human lives.
Not only do natural forests act as biodiversity reserves, they are also carbon sinks keeping carbon out of the atmosphere and oceans.
Urbanisation and Industrialisation: Due to increase population and need of workplace huge amount of residential area and industries are growing everywhere. The ever growing demand of land displaces natural environment consisting of flora and fauna instead of being replaced. Now a days excessive industrial set up is the main cause for air and water pollution. A proper management of industrial growth can provide us a better output for our economy and environment.
Genetic Engineering: Genetic modification of organism and food using biotechnology is called genetic engineering. Genetic modification of food results in increased toxins and diseases as engineered genes become dominant and resistant to antibiotics.
Invention of new viruses are now a common phenomenon. As we all have heard about Ebola virus and Jika viruses, at first are created in nature and then predominate in human body and took several lives.
Loss of biodiversity and species extinction: Human activity is leading to the extinction of species and habitats. The loss and destruction of habitat are major factors contributing to a wave of extinction of species. For example recently the death of last male northern white rhino was all over news and social media.
These species inherently deserve to exist, they also provide product and services essential to human survival.
Few mindful people are focused how we can save our planet in 2050 or how we are going to escape it and colonize another world before earth becomes inhabitable. Maybe they are getting too far and have to focus on something else. If we work hard on new technologies and change our daily lives routine and movements that have power to save the world before its too late.
There are still so many things that we can do to put a dent in what we have already done. By raising awareness through social media, advertisement, verbal communication in local community with family members, friends about the environmental issues, you can contribute to a more environmental friendly and vigilant place for you to live.
