Here are some photos from around the world on the topics ecology, climate change, biodiversity  and education.

Floods at Anuradhapura, Sri lanka, 2011

Traffick congests the cities of the world, puts fertile land under tarmac and pollutes land, air and water. A New Dehli daily occurence

Water hyacinth – an invasive species. Thrives in polluted water. Here Anuradhapura, Sri lanka 2011

Sinyolo Sec school, Kenya. (My old school). The motto is still valid

Composting household garbage. CDM project, Western Uganda

Compost makes fertile grounds for vegetable growing

City garbage dump, Bangkok. Plastics and some other components are difficult to handle

Charcoal burning – a reason behind deforestation. Aberdares, Kenya

Tropical rainforests are shrinking dramatically. West Mau Forest, Kenya

Flamingos Lake Nakuru

Diani beach, Mombasa. Still rich in biodiversity, but coral reefs under constant threat from global warming

Cheetah – an endangered species. Masa Mara, Kenya

Nordeste, Brasil. Endless sugar plantations

Why do we subsidise oil with over USD 500 billion a year? Why do oil and coal business get tax breaks and state guarantees? Put all those resources on renewable energy instead.

Make no doubt about it: Las Vegas is in the desert. Without water it will disappear. Las Vegas gets its water from the Colorado river, the Ogalallah aquifer and Lake Mead. These sources are now rapidly drying out

The South West USA is drying up – and human activity causes it. Many Americans deliberately choose to ignore this fact. Nevada, Arizona are not the only states at risk. Phoenix is one of  the vulnerable cities.

Lake Mead – the biggest water reservoir in the South West.
Changing rainfall patterns, climate variability, high levels of evaporation, reduced snow melt runoff, and current water use patterns are putting pressure on water management resources at Lake Mead as the population depending on it for water and the Hoover Dam for electricity continues to grow.

Grand Canyon, Arizona. Getting drier.

Hoover dam. A 2008 paper in Water Resources Research states that at current usage allocation and projected climate trends, there is a 50% chance that live storage in lakes Mead and Powell will be gone by 2021, and that the reservoir could drop below minimum power pool elevation of 1,050 feet (320 m) as early as 2017 (Wikipedia).

Western Drought Has Lasted Longer Than the Dust Bowl. Dry conditions have drawn down reservoirs, fueled massive wildfires and stunted crops (2021)

Lake Mead is shrinking — and with it Las Vegas’ water supply (CBS Jan 2014)

Dry heat – Colorado (May 2015)

Climate change could kill big US reservoirs
