Question

It is now clear that extreme weather events, global warming, and species extinctions are at least partly caused by pollution, mostly the release of greenhouse gases from power generation, vehicles, agri-business and manufacturing.

Why is the science so widely denied?

Why do many politicians resist implementing policies that will reduce the amounts of CO₂ and methane that are released into the atmosphere?

How are the issues of sustainable agriculture linked to the quality, price, and availability of food?

Answer 1

• Most of the countries are aware of the environmental pollution and many are doing measures to reduce the same.But the science behind the problem is denied by themselves,because of economical impact. Economic impact on nations with control of pollution is heavy.
• Politicians denied implementing policies to reduce pollution because it may adversely affect their economies and they may cause destruction of their vote bank.
• Sustainability of agriculture is important for the quality of products.Its aim is not only production, but their quality,availability and price of the food.By measures for sustainable agriculture, the healthier food can make with low cost.

Actually pollution control measures may feel like Economic burden, but by the actual measures, this can reduce the spending of government. The pollution increases means health of people reduce.That may increase spending on health care system.So by increasing spending in reduction in pollution will result in healthy lifestyle and reduced spending.
