The great nutrient collapse. Irakli Loladze is a mathematician by training, but he was in a biology lab when he encountered the puzzle that would change his life. It was in 1998, and Loladze was studying for his Ph.D. at Arizona State University. Against a backdrop of glass containers glowing with bright green algae, a biologist told Loladze and a half-dozen other graduate students that scientists had discovered something mysterious about zooplankton. Zooplankton are microscopic animals that float in the world’s oceans and lakes, and for food they rely on algae, which are essentially tiny plants.

Scientists found that they could make algae grow faster by shining more light onto them—increasing the food supply for the zooplankton, which should have flourished. But it didn’t work out that way. When the researchers shined more light on the algae, the algae grew faster, and the tiny animals had lots and lots to eat—but at a certain point they started struggling to survive.

"It's a hidden issue,” Ebi said. India has planted nearly 66 million trees in 12 hours. The event took place on Sunday in Central Indian state of Madhya Pradesh. More than 1.5 million people from all walks of life, ranging from students and housewives to government officials, planted a total of 6,67,50,000 tree saplings in just 12 hours. A total of 24 districts of Narmada river basin were identified for the plantation. The saplings included two-dozen varieties of plants sourced from different nurseries around the state. The record of planting maximum saplings was earlier held by Uttar Pradesh, another Indian state, which planted nearly 50 million trees in a span of 24 hours in July 2016. The state chief minister, Shivraj Singh Chouhan said: I am greatly indebted to all who are planting trees today. We will be contributing significantly in saving nature.

The crew of cyclists turning Florida’s lawns into farms | Environment | The Guardian. The future of the immaculate British lawn is under threat, claims a new report from the Royal Horticultural Society: rising temperatures will deliver a triple-threat of dryness, weeds and pests that gardeners will have to navigate if they want to maintain their manicured emerald rectangles. Some reports have even suggested we do away with lawns altogether and just substitute them with fake green turf (gasp!) To avoid the inevitable hassle. But will it be worth it? Let’s be honest, what do lawns really do, anyway—other than satisfy that odd part of the human ego that thrives off the sight of evenly-clipped grass? In fact, how about we really shake things up and just turn our lawns into vegetable patches, instead?

That’s the idea behind Fleet Farming, a group of amateur farmers in Florida who are slowly transforming people’s lawns into food gardens in the city of Orlando. Their approach is simple. It’s also giving lawns an eco-conscious makeover. Recently, they got a grant from the U.S. Decoding Demand for Local Food - Part 2 (Health) In our current series, Localize is exploring the underlying drivers behind local food preferences and the characteristics of local food that are grabbing the attention — and dollars — of consumers. Check out the first post in the series where we discuss: How to give consumers what they want when there is no single definition of 'local.' How local product labeling differs from from fresh to center-store. In this post, we are discussing Health as one of five underlying attributes that drives local product purchasing. There is no concrete evidence that eating local results in better health.

Though, it is hypothesized that local whole foods have a higher nutrition density than comparable products sourced farther away. . • Plant Variety: Large farms prioritize planting crops that offer the highest yeild, grow the quickest, and survive the best when transported long-distances.[2] Short and bitter-sweet — they are choosing quantity over nutritional quality.

Allan Savory: How to fight desertification and reverse climate change. Köppen climate classification. Climate classification system An updated Köppen–Geiger climate map[1] The Köppen climate classification is one of the most widely used climate classification systems. It was first published by the German-Russian climatologist Wladimir Köppen (1846–1940) in 1884,[2][3] with several later modifications by Köppen, notably in 1918 and 1936.[4][5] Later, the climatologist Rudolf Geiger introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system.[6][7] The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns.

The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). Overview[edit] Group A: Tropical climates Group B: Dry climates Group C: Temperate climates Examples (Note. The ethical wardrobe: Is it OK to wear leather? | Fashion.

Whether or not you chose to wear leather usually depends on your stance towards meat, be it vegan, vegetarian or carnivore. The issue of whether or not you are at ease with the practices of the meat industry is one for your own conscience: this column aims merely to provide some facts in an area where there is frequent misconception. Many people happily wear leather on the grounds that it's a byproduct of animal slaughter for meat and therefore a form of recycling - waste not, want not. But is leather really a byproduct? Yes and no. Farmers don't sell hides for tuppence ha'penny out of the kindness of their hearts or from a desire to minimise waste. Take ostrich, for example - in South Africa, ostrich farms are a developing industry. Another oddity is that demand is rising for organic or free-range meats, as an increasing number (though still a tiny minority) of people try to source their food as ethically as possible.
