  We first partially extend a theorem of Topping, on the relation between mean
curvature and intrinsic diameter, from immersed submanifolds of $\mathbb{R}
^{n} $ to almost everywhere immersed, closed submanifolds of a compact
Riemannian manifold. We use this to prove quantization of energy for
pseudo-holomorphic closed curves, of all genus, in a compact locally
conformally symplectic manifold.
