Ledakan populasi
Ledakan populasi atau kelebihan penduduk adalah kondisi terlalu banyak manusia di Bumi sehingga sumber daya yang ada tidak cukup untuk memenuhi kebutuhan mereka.[1] Dengan kondisi saat ini, diperkirakan Bumi masih mampu memenuhii kebutuhan sekitar 11 miliar umat manusia.[2]
Setiap tahun populasi dunia bertambah sekitar 80 juta. Sekitar setengah penduduk dunia hidup di negara dengan sub-replacement fertilty dan pertumbuhan populasi dikarenakan imigrasi.
Menurut Worldometer, per 20 September 2020, total jumlah manusia kurang lebih 7,8 miliar.[3] Perhitungan PBB juga berada pada angka di atas 7 miliar.[4] Kelahiran bayi ke-7 miliar dirayakan PBB pada 2011.[5] Dengan pertumbuhan seperti ini, diperlukan pertambahan sumber daya 70 persen untuk dapat memenuhi kebutuhan manusia pada 2050.[6]
