The capital of the South Asian country Bangladesh, Dhaka, has a population that is booming. However, it stands as one of the world's poorest mega-cities. This report comes from a GlobalPost series about the rise of mega-cities.

Studying macroinvertebrates is one indicator used by scientists to determine water quality in stormwater ponds and natural waterways. Educators and others who work with students can use this hands-on exercise to expand learning outside the classroom by following the simple steps outlined in this video.

In this video Paul Andersen explains how land is developed for human use. Urbanization has occurred through the last century as people have moved to cities in large numbers. Transportation and the arrival of the car have led to urban sprawl and urban blight. Smart growth can be used to mediate some of the ecosystem impacts. Land is also preserved in parks, refuges, and wilderness areas.

Due to the constantly rising demand for food and energy, humanity is consuming more natural resources than are regenerated and brings the Earth's ecosystems to their performance limits. What are the consequences of the rapidly changing land use for humans and the environment? How do future sustainable land use strategies for the limited resource land look like? These are the core questions, which are analyzed interdisciplinary in the Integrated Project Land Use Conflicts.

Mangrove ecosystems provide a multitude of goods and services for people, including: provision of food and clean water (provisioning services), influence climate regulation, soil composition regulation and disaster risk reduction (regulating services), and recreational and spiritual space (cultural services).

To tackle a problem as large as climate change, we need both science and Indigenous wisdom, says environmental activist Hindou Oumarou Ibrahim.

When oil is spilled into the ocean, it has some devastating effects on the ecosystem. How do we clean it up?

In our latest Vox + ProPublica collaboration, we dive into how a structure that's designed to protect us from floods, may actually be making them worse. High levees come at a high cost, often pushing water into communities that can't afford the same protection. To demonstrate, we built a giant, scientific model of a river with levees - complete with adorable tiny houses.
