Divorce - Bad for Environment




Divorce isn't just bad for kids - the environment also takes a beating.

After couples split, more land, energy, and water is used because the parties move into smaller, individual households (more land & resources consumed per person).

What to do? Remarry

Hybrids Not That Green




If you have a buddy who has been letting you know how much more environmentally conscious he is because of his hybrid, tell him to think again. Hybrids like the Prius uses more rare earth elements (REE) than any object in the world. Neodymium and lanthanum, used in a hybrid's batteries and electric motor's magnets, could become extinct in the near future.

With REE used in fiber-optic telecom cables, military gear, computers, etc. hybrids could create a lot of non-ecofriendly situations.

Cooking with the Sun




CNN reports a novel method of cooking cheap enough that it can be readily used in the 3rd world, and will simultaneously help clean the environment.

Jon Bøhmer's 'Kyoto Box' is made of cardboard, a black interior, aluminum foil-covered top panels, and a plexiglass cover, trapping sunlight to cook, bake, clean water and dry food. The box avoids smoke inhalation, fire hazards, and time loss due to the gathering of firewood. It also helps in the fight against carbon emissions, rising energy costs, and deforestation.

So how much of a background in science does one need to help discover the next big green solution? Not much if you have Bøhmer's luck, "This took me about a weekend, and it worked on the first try. It's mind-boggling how simple it is."

Oil Companies Going Green?











Biofuel is the next big thing. The problem is that today's biofuels (ethanol, soybean biodiesel) come with many socio-economic externalities, or harmful side effects.

With fossil fuel consumption having largely contributed to global warming, and biofuel consumption having similar bad side effects, can mankind ever go green? YES.

Teaming up with the likes of Craig Venter, ExxonMobil, among others, has invested extensively into biofuel development - using algae.

Algae, unlike other currently existing biofuels, does not occupy arable land, is extremely cheap, readily available, and consumes carbon dioxide in the process.

To understand the process, check out this short clip.

A Muslim Celebrates Earth Day

Earth Day should be a time for peace-loving people of all persuasions to share their views about the environment and the stewardship of natural resources. Like other great religious traditions, Islamic teachings have placed great emphasis on caring for the environment and for the careful husbandry of shared resources. Moderate, mainstream Muslims reject all forms of terror and violence, and care deeply about their world and its fragility and beauty. In celebration of Earth Day this month, I highlight here a few of the Islamic teachings that relate to these issues, and quote relevant passages from the Holy Qur’an, the sacred scriptures of Islam.

Islam acknowledges the existence of environmental pollution. The Qur’an describes how God demonstrates to humanity how their actions can destroy their surroundings: “Pollution has appeared on land and sea because of what men’s hands have wrought, that He may make them taste the fruit of some of their doings, so that they may turn back from evil.” (30:42).

Islam encourages careful land resource use.

Throughout the Quranic scriptures, we find references to the fact that natural resources are available only in finite quantities that must be carefully sustained lest they become wasted. Muslims are thus reminded of how all bounties are of a proper “measure”: “…He has created everything, and has determined its proper measure” (25:3). Muslims believe that the earth is first and foremost a shared resource that should benefit all of humankind, and that the harvesting of the natural bounties of the earth, such as fruits or crops, should be done with careful regard to not only present but future needs. The Qur’an reminds Muslims of this by stating: “…Eat of the fruit thereof when they bear fruit, and pay His due on the day of the harvest and exceed not the bounds. Surely, God loves not those who exceed the bounds” (6:142).

Islam enjoins believers to respect water resources.

This is also true of water resources, and Muslims are warned not to take supplies of water for granted and are also reminded of why water is a precious resource: “And We sent down water from the sky according to a measure, and We caused it to stay in the earth – and, surely, We have the power to take it away.” (23:19). Elsewhere it is stated:”He it is who sends down water from the clouds; out of it you have your drink, and there grow from it trees on which you pasture your cattle.” (16:11).

The Qur’an reminds Muslims of the ocean’s bounties.

There are many locations in the Qur’an where Muslims are enjoined to reflect upon the blessings they gain from the ocean, whether it is in the form of food within its depths, or from transport upon its waters: “And He it is Who has subjected to you the sea that you may eat therefrom fresh flesh and may take forth articles which you wear as ornaments. And thou seest the ships ploughing through it, that you may journey thereby  and that you may seek of His bounty in other ways and that you may be grateful.” (16:15)

Islam emphasizes stewardship of the Earth.

In many locations it is emphasized that humanity is to act as steward of the bounties it is given. According to Islam, the careful management of resources by humanity is a form of moral trial: “And He it is Who has made you successors of others on the earth and has exalted some of you over the others in degrees of rank, that He may try you by that which He has given you. Surely, thy Lord is quick in punishment; and surely He is Most Forgiving, Merciful.” (6:165).

Earth Day this month reminds us of the blessings we share on this planet, and how with one voice, we should reject fear-mongerers, terrorists, and those who seek to wreak havoc and create discord on our fragile planet, especially in the name of religion. After all, every religious tradition emphasizes the need to respect our planet. Regardless of our political, social or religious persuasions, we are all inside this sacred space and should try to protect it as best as we can.
