The major current environmental problems discussed in the video include pollution of air, water, and soil, global warming, overpopulation, natural resource depletion, waste disposal, climate change, loss of biodiversity, deforestation, urban sprawl, and ozone layer depletion. These issues are caused by human activities such as industrial emissions, overconsumption, deforestation, and pollution from various sources.

The planet is facing unsustainable levels due to shortages of essential resources like water, fuel, and food, exacerbated by the population explosion in less developed and developing countries. Intensive agriculture practices are damaging the environment through the use of harmful chemicals, while overpopulation and fossil fuel consumption contribute to global warming and climate change.

The creation of plastics has led to a global crisis of waste disposal, with developed countries being major contributors by dumping excessive waste in oceans and less developed countries. Nuclear waste disposal poses significant health hazards, while plastic fast food packaging and electronic waste threaten human well-being.
