The number of animals at Gazipur Safari Park has dropped sharply in recent years amid allegations of mismanagement, negligence, and theft.

Many of the animals at the Bangladesh National Zoo are passing days with immense suffering. With poor medical care, scarce food and congested cages, the captive animals look so miserable and weak that seeing them is not exactly fun for all the visitors. However, the zoo, located in a sprawling 186 acres of land in Dhaka's Mirpur section, is the 4th largest in the world in terms of area. With two picturesque lakes, a museum, two camping sites, huge gardens and orchards, this zoo has the potential to be one of the best in the world.

Singapore is creating a vast eco-tourism zone in a bid to bring in more visitors, but environmentalists fear the development will damage natural habitats and are already blaming it for a series of animal deaths.
