Worst Environmental Issues Facing Our Planet

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. I remember when I was around nine years old, I thought that Overpopulation on earth could lead to Earth exploding in space. Yes, I am someone very visionary. - TechnoTarantino

You're a "visionary," alright. After all, Earth is bound to be "exploding in space" any minute now.

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. Heavy metals, nitrates and plastic are toxins responsible for pollution. - TechnoTarantino

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. - TechnoTarantino

If you understood photosynthesis, you'd know that chlorophyll-bearing plants use CO2 during daylight to make sugars and release oxygen as a by-product. At night, when photosynthetic plants grow, they burn that sugar and release...wait for it... CO2. So... do trees cause "pollution? "
