Lagos is home to more than 20 million people. But the city is battling with the threat of rising sea levels. Eko Atlantic is an ambitious project which aims to address the problem. It's a planned city which is to be located on land reclaimed from the sea. But critics say this won't solve the city's environmental problems.

The plan is for this district to house more than 250,000 people and for a further 150,000 to commute here for work. The project is worth billions and is being financed by private investors. The power and water supply will also remain in private hands. It will be an area for the super-rich in what is already one of Nigeria's most expensive cities. It's in stark contrast to the many problems elsewhere in Nigeria, where overcrowding and lack of housing has forced people to build their homes on water.

Abdelaziz Alhamza leads a group called ‘Raqqa is Being Slaughtered Silently.’ It’s an underground organization that smuggles images and videos of IS out of the Syrian city of Raqqa and publishes them abroad. The idea is to document the horrors of life under the rule of the terrorist group.

Members of the group risk their lives to do this work. Some still live in Raqqa, while others have moved to Turkey or Germany. Five years ago, Abdalaziz Alhamza was living the life of a typical student. But the Arab Spring changed everything. Syrians who protested against Bashar al-Assad were imprisoned and tortured. Those horrors were followed by the arrival of Islamic State in Raqqa. Throughout that time, Abdalaziz Alhamza documented what was happening in the city. The 24-year-old became a resistance fighter. But the threat of retaliation from the militant group forced him to leave his home and seek refuge in Berlin. From here, he and others publish material that’s been smuggled out of Syria. Abdalaziz Alhamza is the only public face of the group - that way, only he could become an IS target.

Turtle eggs were long considered a delicacy on India's western coast. But since the beginning of this century, there's been a big turnaround. The olive ridley sea turtle has now been listed as an endangered species and locals in the village of Velas are working to protect it. Thanks to an NGO, residents now collect and preserve the eggs, rather than eating them.

The beaches are also being cleared of plastic waste. These days, they've become a major tourist attraction, with visitors coming to watch the turtle eggs hatch. The animals are now held in high esteem. Since the village doesn't have a history of tourism, locals have offered up their homes to tourists. The program is supported by the International Climate Initiative.

Caribbean lobster are considered a delicacy the world over. But few restaurant customers know that these animals are vital to the ecosystem in the coral reefs and are often caught using environmentally damaging methods.

Biologist Kim Ley-Cooper wants to change that. He's teaching fishermen in Mexico to catch lobster sustainably. At the same time he's collecting scientific data on the reefs.
