World population grows faster than expected

Since 1999, the world's population has grown by about 79 million people a year. A report released today by the World Resources Institute suggests that the world's population is growing more quickly than expected and could reach 9.1 billion people by 2050. The current world population is about 6.8 billion.

Here are some interesting facts from the report, courtesy of The Daily Green:

• More than 95% of population growth is occurring in developing countries, especially in Africa and Asia, regions that account for more than three-quarters of the current population. U.N. demographers estimate that by mid-century, Africa will be adding 21 million people a year to world population and Asia 5 million.

• Although the populations of Japan, Germany, Russia, and some Eastern European countries are already declining, U.N. demographers do not indicate a population peak among industrial countries as a group until 2036.

• Global spending on contraceptive supplies and services totaled $338 million in 2007, considerably less than half the amount in 1995 — despite a 20% increase in the number of people of reproductive age in developing countries.

NIssan's green guru dismisses eletctric car criticisms

Critics of electric cars often say that the argument that electric cars are much better for the environment than conventional cars is undermined by the fact that the cars must be charged using electricity that is likely created by burning fossil fuels.

Andy Palmer, head of the company's green vehicle program, said that even in countries such as the U.S. and China, where the majority of electricity is generated from fossil fuels, an electric car is responsible for 24 to 54 percent less emissions than a conventional car.

Nissan is currently working on its Leaf electric vehicle, which is slated to be released late in 2010. For more info, check out this story from Business Green.

Ozone hole remains the same size

Scientists are telling us that the ozone hole is not closing as they hoped it would after 100 countries signed the historic Montreal Protocol in 1987 that regulated the release of ozone-depleting chemicals worldwide. The hole allows UV radiation to penetrate the atmosphere, leading to an increase in cancer risk and other health and environmental problems.

The good news is that the expansion of the hole has stopped, and scientists still believe that the hole will gradually get smaller as time goes by. As part of the protocol, the release of almost all ozone-depleting chemicals is not only regulated but flat-out banned by the end of next year.

There's a lesson to be learned here. While it's easy for man to cause environmental problems by releasing excess chemicals and carbon into the air, it takes decades, if not centuries, for us to reverse or stop these effects.

EPA recognizes Portland small business

he Joinery, a hardwood furniture producer in Portland, Ore., is getting a green thumbs up from the Environmental Protection Agency for its dedication to fighting climate change by using green power.

EPA is honoring certain Green Power partners across the United States for outstanding contributions in helping grow the nation’s voluntary green power market. The Joinery is being recognized for its dedication to green power purchasing.

The Joinery has long made green power a priority. In 1996, the company purchased wind-derived renewable energy certificates. In 2004, it increased wind power purchase to cover 100 percent of its electricity needs. In 2008, the company bought 280 million kilowatt-hours of green power equal to its entire electricity consumption.

Switch to renewable energy creates jobs

One of the common arguments against switching to renewable forms of energy is that jobs will be lost in the fossil fuel industry. While it's certainly true that jobs would be lost in that industry, a new study by the European Renewable Energy Council and Greenpeace claims that more jobs will be created in new fields than those that are lost.

In addition, the study suggested that a global switch to renewable energy would prevent 10 billion tons of carbon emissions by 2030. If this switch were to happen, employment in the renewable energy industry would increase from about 1.9 million to about 6.9 million, according to the study. The study went on to discuss how job creation in the renewable energy field could be used to combat rising unemployment rates because of the current economic recession.

Cattle diet change could curb global warming

Methane emissions from cattle and other livestock, which are far more potent than CO2 emissions, may be able to be mitigated by additives in the food livestock are fed.

Emissions from livestock make up between 5 and 18 percent of man-made greenhouse gas emissions, depending on who you ask. Methane warms the Earth at about a 20 times faster rate than CO2.

As the Earth's population continues to grow, more livestock will need to be raised to feed the growing population. Previously, the only option seemed to be to give up meat altogether, a stance that environmentalists have long championed. But, experts say that dietary additives could not only reduce methane emissions from livestock but also provide better nutrition for the animals and higher yields to farmers.
