Global Issues of today

The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. Almost all cultures have in some way or form recognized the importance that nature, and its biological diversity has had upon them and the need to maintain it. Yet, power, greed and politics have affected the precarious balance.

Recycling

Recycling of non-biodegradable is just one of the prevention in having pollution.
It can also help the people to be more reliable in practical life.

World debt and Disaster

Poor countries face natural disasters, such as hurricanes, floods, earthquakes, and fires, the cost of rebuilding becomes even more of an issue when they are already burdened with debt. Often, poor countries suffer with many lost lives and/or livelihoods. Aid and disaster relief often does come in from international relief organizations, rich countries and international institutions, but sometimes poor countries are still paying millions of dollars a week back in the form of debt repayment.

Population and feeding the world

The food scarcity part of the argument in the population debate is an interesting one -- people are hungry not because the population is growing so fast that food is becoming scarce, but because people cannot afford it. Food may be scarce, but it is international trade, economic policies and the control of land that have lead to immense poverty and hunger and therefore less access to food, not food scarcity due to over population.

Carbon Sinks , Forest and Climate Change

A mechanism suggested for tackling climate change and warming has been the idea of using “Carbon Sinks” to soak up carbon dioxide. To aid in this, reforestation, or planting of new forests, have been suggested. This is a popular strategy for the logging industry and nations with large forests interests. While there may be some potential in this solution, it cannot be effective on its own. This is because it legitimizes continued destruction of old-growth and pristine forests which are rich ecosystems and have an established biodiversity base (albeit shrinking now) that naturally maintain the environment (at no cost!). Creating new forest areas would require the creation of entire ecosystems. It is also criticized for being a quick fix that does not tackle the root causes effectively and does not lead to, or promote actual emissions reduction.

Loss of biodiversity and Extinction

It is feared that human activity is causing massive extinctions. From various animal species, forests and the ecosystems that forests support, marine life. The costs associated with deteriorating or vanishing ecosystems will be high. However, sustainable development and consumption would help avert ecological problems.
