Are you pro nuclear energy?

Hi,

Are you against nuclear energy?

We need electricity. Clean energy is what we want. Energy from burning coal produces carbon dioxide. Energy from nuclear sources produces nuclear wastes which emit lethal radiations for tens of hundreds of years. It has to stored safely, usually buried underground.

Listen to this debate and make up your own mind.

Plastic bags pollute the environment

Hi,

Australia, South Africa, India, China, Italy, Bangladesh and Taiwan have banned, or instituted partial bans on plastic bags to combat the serious environmental threats they pose. Ireland imposes a tax on each bag, which is another way to slow down their use (after the tax, consumers’ usage dropped 90%). In March 2007, the City of San Francisco was the first major United States city to ban plastic bags, and Oakland soon followed suit

Molecular Genetics, cell divisions, ecology, selection

Hi Students,


Below are a few links I found very useful in understanding concepts in Molecular Biology and genetics. Difficult concepts in cell division are also dealt with.

Ecology, bioaccumulation and bio-magnification are also dealt with in the powerpoints slideshows listed below.



















I will go through these slideshows in class. You may want to browse through them for better understanding.

I do not know if this can be recycled

Hi,

We are sometimes not sure which items to place in our recycling bags or bins.

Zerowastesg has compiled a list of 70 common waste items and checked with the National Environment Agency (NEA) on whether these items are acceptable for recycling through the NRP or recycling bins.

Click at this link http://www.zerowastesg.com/our-initiatives/can-recycle/and find out for yourself.

The recyclables and those that cannot be recycled through the NRP or recycling bins are given. Point and click your cursor on the image and you can see the description of the item with comments from the NEA.

Please do not forget to share this information with all your friends and family.

Cheers
