The threat of exotic species to natural habitats falls into six categories: Most obvious in the Great Lakes-St.
The question is, if we look at it just in food terms, at what level of living? If we're talking about living at food-consumption levels today of, say, the average person in India, then the current world harvest can support 10 billion people.
But if we're talking about the U. And the question is, at what level do people want to live? We look at the poor countries and realize they're not really consuming all that much, but the bottom line is they all want to consume as we do.
And what we're seeing in China today is that desire to consume being realized on a scale we've not seen before.

Will the world be able to support another three billion people, including the offspring of these Malagasy children? Brown says it depends on what standard of living you're talking about.
The combination of advances in living standards and broader access to family planning services are accelerating the shift to smaller families. But now just within the last few years, we've begun to see projections of population being lowered not because of falling birthrates, but because of rising death rates.
In Africa, for example, life expectancy in a number of countries was expected to reach 65 years without AIDS. With AIDS, it's now been dropped, in some of these countries, to something like 47 years, an unprecedented drop in life expectancy affecting hundreds of millions of people.
This is the first time in modern history that we've actually seen such a precipitous drop in life expectancy. That's 15 fully loaded jumbo jets crashing each day with no survivors. We knew that by the late '80s, but it's only been within the last two or three years that the international community and national governments in many of these countries have recognized the threat.
Developing trends The United Nations thinks that India's population will stabilize in this century, meaning that on average it will have two-child families or less. Do you think that's realistic?
When we look at India's projected population, another half billion byI have some real doubts as to whether that half billion will materialize. The question is whether it will not materialize because we get our act together and accelerate the shift to smaller families, or because we fail to do so and water shortages translating into food shortages raise the level of malnutrition and hunger.
If India does not act quickly to stabilize water tables and to accelerate the shift to smaller families, we could see rising death rates because of hunger, in the same way we've seen rising death rates in recent years in Africa because of the failure to control the HIV epidemic.
India's population will soon exceed China's, making it the most populous nation on Earth.
Here, a woman and her children on the streets of Tiruchchirappalli, southern India. It's in the midst of a genuine population explosion, right? Africa's in an interesting situation, because it has the highest fertility of any region in the world, but it has also seen an extraordinary rise in death rates.
We have not yet adequately incorporated the effects of those rising death rates in projections of future population growth in Africa. There are some African countries now in which there are actually projected declines in population once the heavy toll in human life of the HIV epidemic is taken into account.
It does not now seem likely that the population growth that was once projected for Africa will materialize.Climate change is a major environmental concern because of the fact that even small changes can cause significant problems for large portions of the world.
Climate changes are resulting in an increase in the number of worldwide natural disasters like floods and hurricanes. The larger takeaway is that no bag is free of environmental impact, whether that’s contributing to climate change, ocean pollution, water scarcity, or pesticide use.

One of the biggest environmental concerns in the Central American region is the protection of the tropical rain forests. Even though Central America is a relatively small region, it has an abundance of rain forests, but as the years pass by, there's major environmental concerns about their well being, and even about their existence.
