education and population - Sir Crispin Tickell
Our society is faced with a rich set of problems. Since the beginning of the industrial revolution 250 years ago, our species has changed the nature of the land surface, oceans and atmosphere. Therefore, the increasing use among geologists of the term after the Anthropocene epoch Holocene
Of all the problems we face interconnected, perhaps the most serious is the proliferation of our species. Our numbers have increased by about one million 12,000 years ago around one billion 250 years ago. Since then there has been an extraordinary acceleration of 2 million in 1930 to 6,000,000,000 at the end of the century and now has nearly 7 million.
In trying to resolve this issue, the role of education, especially women, is essential. When women were granted equal status with men in general, when there is a provision for old age, when they can use contraception, especially if it is filed as full citizens, a human fertility decreased: in many industrial countries below the replacement rate and partly by a considerable margin. At the same time, people are living longer, this creates problems, and the introduction of new technologies, the risks of rising unemployment. Over half of our species lives in cities, and has been described recently as a nest of super-control. Now we need to address these issues in all their breadth and complexity.
-Jo Royle Oceans
With every breath we take and the drop of water we drink, we are connected to the ocean. Sixty-two percent of our planet is the ocean. The sea makes the climate system, it absorbs the heat generated by our reliance on fossil fuels is the main source of protein for over a quarter of the world population.
live in a blue planet. The ocean breathes for the planet, with most of the photosynthesis occurring on the surface of the sea more than any other. The health of future generations depends on the health of our oceans. However, in silence and out of sight, the deep blue is the suffering of our decision to bring to the relationship. We are dangerously close to the sea reached its capacity to act as a sink for carbon largest planet. The depletion of ocean fisheries, toxic pollution of waters by industrial waste and pollution and acidification are the main threats plastic health of the global population.
The oceans are clearly of great importance to energy security, economic and food and drinking water. The blue planet teaches us about love, beauty, respect, sensuality and mystery. Ocean fuels our curiosity, imagination, well-being and gives us a sense of clarity, meaning and purpose - the most important liquid in the world is master. We would get the same feeling of peace research in an ocean without life?
water - Daniel Yeo
We can all relate to water- and every traveler can talk about contaminated water and sanitation, including the Commonwealth Games English team, and even in developed countries. Having the courts can do to some embarrassing stories, but it's not a joke that diarrhea is the leading cause of death among children in sub-Saharan Africa. Preventable diarrhea associated with dirty water and poor sanitation kills more children than AIDS, malaria and tuberculosis combined.
And not just children - the water is primarily a gender issue. Women and girls bear the greatest burden - to walk long distances in rural areas, queuing for hours in line in urban slums
low water, sanitation and hygiene undermines maternal and child health and nutrition.
Education - 443m school days are lost to water-borne diseases. Girls are more likely to remain in schools with separate toilets for women.
These gaps in human development at a cost to the economy, through the lives lost, school days, work days and the burden on health systems. The World Health Organization estimates that every $ 1 invested in water generates $ 8 in higher profits.
What makes humans different from animalsis that we are the only species to exploit the power of the things I do not eat.
use external energy is fundamental to being human. And use more energy throughout history has been the key to a better quality of life -. More food, better transport, households hot (or cold) and offices Our success as a species has led to a number of people out of control, out of control and energy use per capita. Multiply the two together and you hit the buffers.
